Rotary vane pumps from the Pascal Series for backing vacuum and medium vacuumThe single-stage Pascal rotary vane pumps are the result of decades of experience in the design and industrial production of vacuum pumps.

Rotary vane pumps for main vacuum applicationsThe pumps from the Pascal Series from Pfeiffer Vacuum with their high performance are used in the most demanding applications in industry, analytics and research & development. They are distinguished by their recognized high quality and reliability.SD versions are available for all vacuum applications with non-corrosive gases.Rotary vane pumps for simple integration in systemsThe oil emission on the outlet is minimized through the optimal lubrication design. The integrated non-return system guarantees optimal leak-tight properties by design. The assignment of all operating elements and service accesses on the front side of the vane pumps guarantees a simple integration in systems. These compact models are equipped with universal motors, which allow for worldwide usage. The configuration of the single stage motors occurs through a simple plug-in position.Long-lasting rotary vane pumpsJust like all products from Pfeiffer Vacuum, with its robust design the Pascal Series is designed for maximum reliability and minimal maintenance. The external shaft seals can be easily exchanged without disassembling the pump. Thus, all pumps can be simply maintained in the field with the fitting original maintenance sets. A comprehensive selection of accessories like oil filters, condensate traps or dust filters add to the pump selection. Fitting lubricants with different viscosities guarantee the optimal and long-lasting operation in different applications. In order to obtain the desired final pressure, the operating fluid must have a very low saturation pressure and a special viscosity in the internal temperature range of the pump.AdvantagesTwo pumping speeds: 5 m3/h and 15 m3/hKnown worldwide for high quality and reliabilitySimple application and integrationSimple maintenanceDesign with low oil back-streamingOptimized global tightness conceptCE-/UL-/CSA-permitted motors
